Analysis of photovoltaic array fault and aging based on single diode model

Photovoltaic (PV) power plants are located in more complex environmental conditions, and PV modules are prone to failures. In order to detect and take appropriate techniques to troubleshoot the faults in time, and to detect and diagnose the PV system faults effectively, this research primarily concentrates on utilizing MATLAB simulations to conduct an in-depth analysis of PV arrays and to identify fault characteristics under various conditions using a single-diode model. By employing this model, different faults occurred in PV arrays are effectively diagnosed. The study not only provides a comprehensive analysis to faults in PV cells but also offers a robust scientific foundation for subsequent maintenance and optimization efforts. Consequently, this enhances both the overall capacity and the economic benefits in PV systems.
